Welltest 102: Production Test Reporting

Production testing is a generic term for #welltesting through portable facilities. Usually production testing is done prior to tie-in for commercial operations. Production tests clean up wells and help define deliverability or productivity for economics and facility design. Production testing includes: Underbalanced drilling; when wells are allowed to flow while drillingFracture stimulation treatment; sand and fluid clean-up operationsAcid wash or squeeze stimulation treatment; fluid clean-up operationsVarious well workover, clean-up, and...

Calgary Flood News

We would like to extend our sympathy and understanding to all of our fellow Calgarians during this unprecedented natural disaster. This catastrophe has obviously impacted everybody in our community, and the economic ripples will be felt across Canada. My parents were amongst the thousands evacuated from Sunnyside, and are presently staying with us until electricity and sewer services are restored. Welltest Specialists is fortunate to be high and dry, our technology is fully operational, and our virtual office is open for business as usual. If...

Perforation Inflow Diagnostic Tests

Perforation Inflow Diagnostic (PID) Tests are an excellent, and cost effective, method for obtaining a quality estimation of initial reservoir pressure conditions. As the name implies, these tests are conducted during or immediately after perforating – so reservoir pressure transients are limited. Subsequent completion, stimulation, clean-up, and testing operations often seriously affect our ability to acquire quality pressure build-up data for analysis. Using subsurface pressure recorders will also satisfy ERCB Initial Pressure Gas (IP...

Diagnostic Fracture Injection Testing (DFIT)

Characterizing Reservoir Properties using Diagnostic Fracture Injection Testing (DFIT) was presented at a recent Society of Petroleum Engineers (SPE) luncheon. A great talk – and a great reservoir diagnostic test – as our example Level 2 eREPORT illustrates: DFIT2 Mini-frac’ Fall-off. But…here in Alberta…as per ERCB Bulletin 2010-38 surface (or acoustic well sounder) data are no longer acceptable for Initial Pressure Gas or Initial Pressure Oil requirements. For compliance with Initial Pressure requirements the...

Sample eREPORTS Uploaded

We now have a variety of sample eREPORTS available for perusal. The first one I’d like to draw your attention to is titled PTA1 Comprehensive: Pressure Transient Analysis level 1 comprehensive. This is the traditional, legacy style, turnkey eREPORT for reservoir engineering, reserve auditors, and data rooms – with robust analytics, petrophysical, logs, completion reports, deviation, fluid properties, reserves, and Board certificates, all in one place. The write-up is thoroughly inclusive: objectives, conclusions, background, data...
